[Saliency] Enable Java/Android bindings by adding 'WRAP java' to CMake opencv#4018 Fixes opencv#4016 This addresses the inability to use the `saliency` module in Android (Java/Kotlin) applications. When generated using `build_sdk.py`, the native library compiles, but the Java wrapper class (`org.opencv.saliency.Saliency`) is not generated. # Technical Fix: The `ocv_define_module` macro in `modules/saliency/CMakeLists.txt` was missing the `java` flag in its `WRAP` parameter. **Change in `modules/saliency/CMakeLists.txt`:** **OLD** ocv_define_module(saliency opencv_imgproc opencv_features2d WRAP python) **NEW** ocv_define_module(saliency opencv_imgproc opencv_features2d WRAP python java) ### Pull Request Readiness Checklist See details at https://github.com/opencv/opencv/wiki/How_to_contribute#making-a-good-pull-request - [x] I agree to contribute to the project under Apache 2 License. - [x] To the best of my knowledge, the proposed patch is not based on a code under GPL or another license that is incompatible with OpenCV - [x] The PR is proposed to the proper branch - [x] There is a reference to the original bug report and related work - [ ] There is accuracy test, performance test and test data in opencv_extra repository, if applicable Patch to opencv_extra has the same branch name. - [x] The feature is well documented and sample code can be built with the project CMake

Fix clahe build ### Pull Request Readiness Checklist Fix the build related to this [PR](opencv/opencv#28014). This inherits from CLAHE, so the `setBitShift` and `getBitShift` functions need to be defined. Error this fixes: ``` error: invalid new-expression of abstract class type '{anonymous}::CLAHE_Impl' opencv/contrib/modules/cudaimgproc/src/histogram.cpp:150:11: note: because the following virtual functions are pure within '{anonymous}::CLAHE_Impl': class CLAHE_Impl : public cv::cuda::CLAHE In file included from opencv_contrib/modules/cudaimgproc/include/opencv2/cudaimgproc.hpp:51 opencv/modules/imgproc/include/opencv2/imgproc.hpp:1074:26: note: 'virtual void cv::CLAHE::setBitShift(int)' CV_WRAP virtual void setBitShift(int bitShift) = 0; opencv/modules/imgproc/include/opencv2/imgproc.hpp:1080:25: note: 'virtual int cv::CLAHE::getBitShift() const' CV_WRAP virtual int getBitShift() const = 0; ``` This change was tested on Ubuntu 24.04 with the latest updates from the opencv and opencv_contrib repositories. This resulted in the build being successful. - [x] I agree to contribute to the project under Apache 2 License. - [x] To the best of my knowledge, the proposed patch is not based on a code under GPL or another license that is incompatible with OpenCV - [x] The PR is proposed to the proper branch - [x] There is a reference to the original bug report and related work - [x] There is accuracy test, performance test and test data in opencv_extra repository, if applicable Patch to opencv_extra has the same branch name. - [x] The feature is well documented and sample code can be built with the project CMake
